This seemingly new aftermarket product, "G40 Zerex" appears to be a match to the genuine Porsche coolant, which I noticed was available at O'Reiley auto parts in the US.

As it's diluted by being pre-mixed 50/50, and costs $22/gallon, though, it's not much of a cost savings over genuine Porsche coolant.

Can't say if it's exactly the same, but it is a G13 mix that is the same colour that is at least compatible.
Been running with this stuff for 2 years, and at $32/ galllon, my wallet likes it too.

For $32 a gallon, you could have had the real thing: Sunset Porsche Parts

I'm not talking US funds... Porsche coolant is over $50 per gallon with my PCA discount. We get shafted on this side of the border.

I bit he bullet. Porsche coolant. $53. Does PCA get a discount at Sunset?

Yes...................

and bagged milk as well

This is Pentosin's Pentofrost and it's what I use in my VW TDI. I highly recommend it. You can buy it at Advanced Auto Parts. It's used by VW Dealers. It's recommended for all aluminum engines. I am needing to flush my PBS and I will be using what I still have on the shelf.

Lol. I confused Sunset with Suncoast. Oops

Why mess around to save so few $

I agree. OEM coolant and be done with it.

Country Time with a sprig of mint. Make sure you get the sugar free and only use distilled water.

I agree too. Better safe than sorry. Picked it up from Porsche yesterday.

Sunset vs Local Dealer
 

Just purchased a gallon at my local Porsche dealer (Jackie Cooper) in Tulsa on my lunch hour. $48.88 + tax = $53.04.

Sunset with shipping to OK was not a savings. Too bad - I like to give them the business.

I have no relation or interest in that company

OEM equivalent coolant
 

For those of us living in Canada, you can use this from Canadian Tire OEM Vehicle Specific Coolant, Volkswagon, Audi | Canadian Tire

I know that the Porsche/VW/Audi version is imported from Europe, but not sure who the specific manufacturer is. I haven't used this on my Boxster, but I used some of their other versions in other cars and all I can say is that they sure have some pretty colors :)

Wow. At that price it is a steel.

This is what I use. Great stuff
